Answer 2

Answer:

Answer:

The steps are shown below:

Step-by-step explanation:

We can draw the area model for 2-digit by 2-digit multiplication by using the following steps:

Step 1: First write the multiplicands in expanded form.

For example: 26 as 20 and 6, and 36 as 30 and 6.

Step 2: Now, Draw a 2 × 2 grid, and write the terms of one of the multiplicands on the top of the grid. One on the top of each cell.

Step 3: Write the terms of the other multiplicand on the left of grid.

Step 4: Write the product of ones and tens in respective cell.

For example: 26×36

20 6

30| 600 180

6 | 120 36

Now add them: 600+180+120+36=936

Salid bought 35 feet of window trim at a hardware store. The trim cost $1.75 per foot, including sales tax. If salid paid with a $100.00 bill, how much change should he have received?

Answers

first we have to write down what we know and that is 35ft of window trim is what he has and for each foot of the 35 is a $1.75. so-->35(1.75)--> this is 61.25 or $61.25. He used 100.00 to pay so he did not use all of the 100. 100-61.25= is how much salid should recieve back which is $38.75.

If you would like to know how much change should Salid have received, you can calculate this using the following steps:

35 feet * $1.75 per foot = 35 * 1.75 = $61.25

$100.00 - $61.25 = $38.75

Result: Salid should have received $38.75.

What is negative 4 minus negative 2?

Answers

-4 - (-2) = -4 + 2 = 2 - 4 = -2

The value of the verbal expression is -2.

Given that a verbalexpression negative 4 minus negative 2, we need to solve this,

To subtract a negative number, you can rewrite it as adding the opposite. Therefore, "negative 4 minus negative 2" can be rewritten as "negative 4 plus positive 2."

When you add a negative number and a positive number, you can simply combine them by their absolute values and use the sign of the larger number. In this case, the absolute values of 4 and 2 are the same, so the result will have the same sign as the larger number, which is negative.

Therefore, "negative 4 plus positive 2" equals -2.

So, negative 4 minus negative 2 is equal to -2.

Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04

Now find the area of the other one.

Area = πr²
A = 3.14 * 0.75²
A = 1.76625

Now subtract them.

113.04 - 1.76625 = 111.27375
Now, we have our answer: A = 111.27375

However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.

Answer:

Area = πr²

Area = 3.14* 6²

A = 3.14 * 36

A = 113.04

Now find the area of the other one.

Area = πr²

A = 3.14 * 0.75²

A = 1.76625
